为什么我无法在控制台应用程序下将System.IO添加到引用中 [英] Why I can't add System.IO into reference under Console application

问题描述

我是一名新的C＃播放器。



我尝试创建非常简单的控制台应用程序，可以帮助我在引用中添加字符串。

但我发现我找不到System.IO来添加参考。结果我可以在程序中说Using System.IO，结果我不能使用streamwriter类。



有谁能帮我弄清楚出了什么问题？

Hi, I am a new C# player.

I try to create very easy console application that can help me add strings inside reference.
But I found I couldn't find System.IO to add to reference. As a result I can say "Using System.IO" in program, as a result I can't use streamwriter class.

Can anyone help me to figure out what is wrong?

推荐答案

StreamWriter是MSCORLIB的一部分.DLL程序集，应该已经为你引用了System.Core： https://msdn.microsoft.com/en-us/library/system.io.streamwriter(v = vs.110）.aspx [ ^ ]



因此，如果您的应用程序是一个完整的Windows应用程序（某些移动框架更加有限），StreamWriter应该可用。



当然，我可以在我的控制台应用程序中使用StreamWriter。



所以 - 首先检查案例：StreamWriter与Streamwriter不同或者编程，只有第一个才能工作。

如果可以的话：

StreamWriter is part of the MSCORLIB.DLL assembly, which should be already referenced for you unsed "System.Core": https://msdn.microsoft.com/en-us/library/system.io.streamwriter(v=vs.110).aspx[^]

As a result, StreamWriter should be available, provided your app is a "full" Windows app (some of the mobile frameworks are rather more limited).

Certainly, I can use StreamWriter in my console apps.

So - start by checking the case: StreamWriter is not the same as Streamwriter or streamwriter and only the first will work.
If that's ok:

StreamWriter sw = new StreamWriter(path);

检查您的项目属性，并确保您没有使用其中一个可能不包含它的有限框架。

Check your project properties and make sure you aren't using one of the "Limited" frameworks which may not contain it.
